PRINTING ATTACHMENT FOR PA PER- ROLL HOLDERS.

SPECIFICATION forming part of Letters Patent No. 439,221, dated October 28, 1890.

Application filed June 16,1890- Serial No.355,546. (No model.)

To all whom it may concern:

Be it known that I, GEORGE C. WESTER- VELT, a citizen of the United States of America, residing at Marseilles, in the county of La Salle and State of Illinois, have invented certain new and useful Improvements in Printing Attachments for Paper-Roll Holders, of which the following is a specification, reference being had therein to the accompanying drawings and the letters of reference thereon, forming a part of this specification, in which- Figure 1 is a central vertical cross-section of the paper-roll holder and its attachments complete, and Fig. 2 is a perspective View of the swinging inking-trough and its inkingroller.

This invention relates to certain improvements in a printing attachment for a paperroll holder, which improvements are fully set forth and explained in the following specification and claims.

Referring to the drawings, B is a roll of paper wound on a shaft j ournaled at each end in the posts A of the frame, which posts are secured at their base in the base-pieces B, and connected with each other at their upper ends by means of the cross-bar D.

R is a distributing-roller, and R R are plain rollers, the roller R resting and rolling on the paper-roll B. These rollers all journal at each end in a channel-box in frame F, having arms E detachably connected to the crossbar D by means of set-screws a.

R is an inking-roller arranged to roll in the ink-trough T and journaled at each end in the ends of said trough, so it can rotate therein. Said trough is for holding ink for supplying the inking-roll B. with a sufficient quantity of ink in such manner that the inking-roll may roll in the ink.

R is a printing-roller interposed between its ends turned downward to rest upon the,

journals of the distributing-roller R. It is intended that the said shield J shall be attached to the said cross-bar r, so it will not be displaced in use, and for such purpose maybe soldered thereto or secured in any other suit able manner, the precise manner not being important. If soldered together, the channelboX in frame F is of sufficient size so the turned-down ends of rod r can oscillate to some extent therein, so the ink-roll B may be brought in contact with the distributing-roll. By thus suspending the ink-trough and its roller the inking-roller is not in contact with the distributing-roller, but may be brought in contact therewith by swinging the trough forward, as shown in the broken lines in Fig. 1, when necessary to supply the distributingroller with ink. The upper edge of said curved shield J is weighted by means of a rod w or other suitable means, so as to overbalance the weight of the ink-trough and its roller and" hold the inking-roller out of contact with the distributing-roller, except at such times as it is necessary to supply it with ink. Said shield not only serves to suspend the said ink-trough, but covers and protects all the rollers from dust and other accumulations.

R is an impression-roller, againstwhich the printing-roller R prints, the paper being passed between said rollers ofi the roll B. The roller R is introduced between the paper-roll B and the impression-roller R for the pur pose of causing the impression-roller to rotate in the same direction as the paper-roll B.

It is found necessary to use an impressionroller between the printing-roller and paperroll for the reason that in handling and shipment the paper-roll often becomes dented and injured, so that portions of the paper cannot be printed in case the printing-roller printed directly on the paper-roll. The impressionroll furnishes always a perfect surface on which to print, and in case it should fail in that regard a new one can be introduced; also, by the use of the two rollers R R the paper as it passes from the roll over the impression-roll is prevented from running to one side, as is the case when an impression-roller is used out of contact with the paper-roll.

In operation the paper P is passed from the roll B over impression-roll R and between it and the printing-roll R and from thence to and in contact with the opposite side of the roll B, and from thence under the roller R below the paper-roll B, and from thence out under the swinging cutting-blade S, as shown, and as it is drawn along through the machine is printed by the printing-roll. The channelbOX in the frame F permits the rollers and the inking apparatus to follow up the paperroll as it diminishes in size until it is all unwound.

Havingthus described myiuvention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. The combination, with the frame AF and the paper-roll shaft, of the distributing-roll R, print-roll R impression-roll R idle-roll R ink-trough T, and ink-roll R, arranged in said trough, the said trough being adapted to swing and bring its roll in contact with the distributing-roll, substantially as and for the purpose set forth.

2. In the printing attachment for paper-roll holder shown and described, the combination of frame F, swinging shield J, having its lower part formed in an ink-trough T, ink-roll R, arranged in said trough, and cross-bar 'r, for supporting said shield and trough, and the distributing-roll R, substantially as and for the purpose set forth.

3. In aprinting attachment for a paper-roll holder, the combination of a printing-roll, an impression-roll, a distributing-roll, and an inking-roll arrangedin an in k-trough, adapted to swing in contact with the distributing-roll, substantially as and for the purpose set forth.

4. In the printing attachment for a paperrollholder, the curved shield J, carrying an ink-trough and ink-roll and adapted to swing and carry its ink-roll in contact with the dis tributing-roll, substantially as and for the purpose set forth.
